The formation and destruction of the continental root is one of the most important going topics on the solid earth sciences. A series of deep-seated xenoliths, including mafic to felsie granulite, eclogite, metagabbro, pyroxenite and peridotite, from the Xinyang area with unique temporal and spatial meaning, at southern margin of the North China, were used to dating in ages and properties. The geometrical model of the zonal lithosphere structure in age and composition were suggested for the conjoint position of multi-blocks in Mesozoic (~160 Ma). Basing on the zonal lithosphere, the authors also discussed the dynamic processes for its formation.
